2.4 Demand-side and supply-side policies Flashcards
What are the two types of macroeconomic policy that a state can implement?
- Demand-side policies
- Supply-side policies
Define: demand-side policies
Policies that focus on changing/shifting aggregate demand in an economy to achieve objectives.
What is a discretionary policy?
A policy involving active and purposeful intervention from the government to influence aggregate demand.
The policy is at the discretion (choice or will) of the government.
What are the types of discretionary demand-side policies?
- Fiscal policy
- Monetary policy
What are non-discretionary policies?
Policies that rely on automatic stabilisers instead of direct government intervention.
What are stabilisation policies?
How is this shown on the business cycle graph?
Fiscal or monetary policies that attempt to reduce short-run fluctuations of the business cycle, as they seek to ‘stabilise the economy’
The peaks and troughs are flattened.
What is fiscal policy?
Policies that manipulate government expenditures and taxes to influence the level of aggregate demand.
What are the sources of government revenue?
(3)
- Taxes of all types
- Sale of goods and services (e.g. public goods)
- Sale of government-owned property or enterprises
What are the types of government expenditure?
What do they mean?
(3)
- Current expenditure: Government’s day-to-day spending (e.g. wages, NHS, schools etc.)
- Capital expenditure: The production of physical capital (e.g. roads, ports, HS2 etc.)
- Transfer payments: Taxes to welfare
Define: Government budget
A type of plan of a country’s tax revenues and expenditures over a period of time (usually a year).
What is:
- A balanced budget
- A budget deficit
- A budget surplus
- If taxes are equal to expenditures over the budget period
- If expenditures are greater than taxes over the budget period
- If taxes are greater than expenditures over the budget period
What components of aggregate demand can fiscal policy affect?
- Level of the government spending (G)
- Level of consumer spending (C)
- Level of investment (I)
What is expansionary fiscal policy?
Fiscal policy that seeks to increase output (usually to close a recessionary gap and to achieve slow and stable growth)
What might an expansionary fiscal policy consist of?
- Increasing government spending
- Decreasing personal income tax
- Decreasing corporation tax
- A combination of increasing spending, and decreasing tax
What is contractionary fiscal policy?
A policy that attempts to decrease (or the rate of) growth (usually to close an inflationary gap).
Shifts AD left
What might a contractionary fiscal policy look like?
- Decreasing government spending
- Increasing personal income taxes
- Increasing corporate taxes
- A combination of decreasing spending and increasing taxes (austerity)
What is the ratchet effect in the Keynesian model?
The price level moves up when AD increases and remains at the same level until there is a further increase in AD.
(PL cannot move down once moved up)
What are automatic stabilisers?
Examples?
Automatic stabilisers are factors that automatically, without government intervention, work towards stabilising the economy.
Examples: Progressive income taxes, Unemployment benefits.
Explain how progressive income taxes act as automatic stabilisers during both inflationary and deflationary parts of the business cycle?
Inflationary: as real GDP rises, so do incomes. Therefore, government tax revenues automatically increase, causing disposable (after-tax) income to be lower than it otherwise would be, creating downward pressure which dampens the boom.
Deflationary: as real GDP falls, so do incomes. Therefore, government tax revenues automatically decrease, causing disposable (after-tax) income to be higher than it otherwise would be, creating upward pressure which dampens the bust.
How does the progressiveness of a tax system tie into the effectiveness of its function as an automatic stabiliser?
The more progressive a tax system is, the greater the stabilising effect on economic activity.
Explain how unemployment benefits act as automatic stabilisers during both inflationary and deflationary parts of the business cycle?
Inflationary: as real GDP rises, unemployment falls, and so the number of people claiming benefits. Therefore, they receive less income than if they were employed and receiving benefits, creating downward pressure on a boom.
Deflationary: as real GDP falls, unemployment rises, and so do the number of people claiming benefits. As they have more disposable income than they would if they were unemployed and there would be no benefits, and able to consume and demand, creating upward pressure on a bust.
How is the effectiveness of fiscal policy linked to the Keynesian multiplier?
The effectiveness of fiscal policy is affected by the size of the multiplier:
- the larger the multiplier, the stronger the impact of the policy on real GDP
- also, an increase in government spending has a larger impact on AD than a decrease in taxes.
What is the Keynesian multiplier equation and what are the components?
MPC + MPS + MPT + MPM = 1
MPC = Marginal propensity to consume
MPC = Marginal propensity to save
MPT = Marginal propensity to tax
MPM = Marginal propensity to import
How can you calculate the Keynesian multiplier?
Multiplier = 1 / (1 - MPC)
What does a Keynesian multiplier of X mean?
That if the government increases spending by 1, it follows that AD will increase by X.
E.g. if X=4, that a spending increase of $2 would cause a shift in AD of $8
